SAFETY APPLIANCE FOR RAILWAY-TRAINS.

Specification of Letters Patent.

Patented Oct. 13, 1914.-

Application filed March 1, 1913. Serial No. 751,525.

To all whom it may concern:

Be it known that we, CLAnENoE E. BAUMER and JoI-IN CORREY, citizens of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improve- I ments in Safety Appliances for Railway- Trains, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to a safety appliance for railway trains, and the principal object of the inventionis 'to provide a device which maybe connected with the air brake lever and automatically operated to apply the air brakes in case the engineer runs by a danger signal.

Another object of theinvention is to provide an improved track device for operating the mechanism carried by the train.

. With these'and other objects in view this tary view showing the pawl and ratchet which holds the worm shaft in a set posi tion.

In the accompanying drawing the nu morals 10 and 11 indicate the railroad rails which are mounted upon the ties 12 and secured thereto by the usual spikes. A bar 13 is rotatably mounted in bearings 14 carried by the rails 10 and 11, and has one end portion extending beyond the rail 11 and bent to form a lever handle 15. This lever handle is provided with an opening through which a cable 16 passes so that when the cable is moved by the station master the knobs 17 carried by the cable will be brought into engagement with the lever, thus causing the lever to be moved to rotate the shaft 13. This cable passes around a pulley wheel 18 mounted on the pin 19 of the bracket 20 secured to one of the ties 12. It will, therefore, be seen that when the station master sets the signal that the cable 16 which is connected with the signal will move easily.

Plates 21 are rigidly mounted upon the shaft 13 and are intended to engage the pendulum of the device mounted upon the engine to operate the engine device. From an inspection of Fig. 2 it will bereadily seen that when the plates 21 are in the lowered position shown in full lines that the pendulum may pass over them without striking them, but that when the plates are raised to the position indicatedby dotted lines that the end of the pendulum will. strike the plates, thus causing the train mechanism to be operated.

In the accompanying drawings all of the engine has been omitted excepting the boiler which is indicated by the numeral 22 and shown in end elevation in Fig. ,1. A frame 23 is secured to the boiler and extends to one side so that the brake operatingmechanism may be connected with the airbrake operating lever 24 located in thefien gineers cab.

A disk 25 is secured to a, shaft passing through the bearing'26 and isprovided with lugs 27 positioned upon opposite sides of a link 28 rotatably mounted upon the shaft above the disk 25. In order to rotate the disk carrying shaft there is provided a gear wheel 29 which is rotated by the worm formed upon the worm shaft 30. This worm shaft is rotatably mounted in bearings carried by the bracket 23 and carries a beveled gear 31 which meshes with a beveled gear 32 rigidly secured to the upper end of a vertical shaft 33. A horizontal shaft 34 is also rotatably mounted in bearings carried by the bracket 23 and is provided at its outer end with a beveled gear 35 meshing with a beveled gear 36 at the lower end of the vertical shaft 33. The pendulum 37 which is engaged by the plates 21 has its upper end formed into a beveled gear 38 which is rotatably mounted upon a stub axle 39 and meshes with a beveled gear 40 mounted upon the inner end of the horizontal shaft 34'. It will, thus be seen that when the pendulum strikes the plates 21, the shaft 34 will be caused to rotate and in its turn rotate the shaft 33. The shaft 33 rotates the worm shaft 30 which causes the gear 29 to be r0- tated and thus the disk 35 will be turned to move the lever 24 to apply the air brakes.

From the above description the operation of this device will be readily understood, it

said shafts being provided with a worm,

ing the air brakes. It should be noted that if desired one of the plates 21 may be omitted as two plates would only be neces-' sary in a single trackline. A counterweight 4:1 is provided and extends from the head 38 to act as means for overcoming to a certain extent the tendency of the pendulum 37 to return to its normal position'after being thrown to a raised position by the plate 21. In order to releasably hold the shaft in aset position, a pawl 42 is pivotally mounted upon an arm 43 extending from the bearing tt and engages a ratchet wheel 45. This pawl will hold the worm shaft 30 in the set position and will act as additional means for preventing the pendulum from swinging down to its normal position. A suitable line or other device may be connected with the eye 46 to per mit the pawl to be moved out of engagement with the ratchet wheel, and thus permit the pendulum to swing down to its normal position, thus releasing the air brakes.

Having thus described the invention what is claimed as new, is

1. In a train stopping mechanism, the combination with a support, of a frame car ried by saidsupport, said frame provided with journals, shafts mounted in said journals, gearing connecting said shafts, one of an air brake operating device positioned above said worm and carried by said frame, said air brake operating device comprising a shaft, a gear attached to the lower end of said shaft and meshing with said worm, a disk attached to the upper end of said shaft, means for pivotally connecting said disk to an air brake operating lever, and an operating device connected to one of the shafts whereby motion may be imparted to all of the shafts, said worm and said air brake operating lever.

2. In an apparatus of the class described, the combination with a support, of a rectangular frame attached to one side of said support, said frame being provided with a lower and a side and a top set of extensions, each set of extensions being provided at their outer ends with journals, a series of shafts carried by said journals, meshing gears on said shafts,the shaft journaled in the upper set of extensions being provided with a worm positioned between the contiguous faces of said extensions, said frame being provided with an air brake operating lever, a bracket overhanging said worm, a journal formed in a vertical position upon the outer end of said bracket, a shaft in the journal of said bracket, a gear carried by the lower end of said shaft and meshing with said worm, said last-mentioned shaft being provided with a disk upon its upper end, pivotal air brake connecting means attached to said, disk, and means for operating the shaft in the-lower set of extensions for operating all the shafts and said disks and airbrake connecting means.

In testimony whereof we hereunto affix our signatures in presence of two witnesses.
